v sT A STOVEPIPE-FASTENER.

Specification of Letters Patent.

Application filed July 23, 1913.

Patented Mar. 17, 1914. Serial No. 780,704.

To all whom, it may concern Be it known that I, WILLIAM C. PRATT, acitizen of the United States, residing at Augusta, in the county ofWoodrulf and State of Arkansas, have invented a new and usefulImprovement in Stovepipe-Fasteners, of which the following is aspecification.

This invention relates to a fastening device for stove pipes and theobject of the invention is to provide means for securely holding thepipe within the flue thimble and also to allow proper adjustment so thatthe device can be employed with chimney walls of different thicknessesand also with stove pipe wall flanges of various sizes.

The invention consists of the novel features of construction hereinafterdescribed, pointed out in the claims and shown in the accompanyingdrawings in which,

Figure l is a vertical longitudinal section. Fig. 2 is a plan view. Fig.3 is a section on the line 33 of Fig. 1. i

In these drawings, 1 represents the pipe opening and 2 a suitablethimble adapted to be inserted in said opening. A stove pipe 3 fitswithin said thimble and carries upon its top a suitable plate A rivetedor otherwise secured in place, to which is connected a verticallyarranged guideway 5, said guideway being formed by bending or folding astrip of sheet metal lengthwise into a U- shape with a rounded bottom,the guide-way 5 so formed being provided with alining notches 6 alongits upper edge, and the side members of said guide-way are cuttransversely adjacent one end, the said end portion being bent into ahorizontal plane thereby forming a tongue 5 and these tongues are formedat opposite ends and upon opposite sides of the guide-way, one of thetongues being riveted to the pipe and the other to the plate A. A plate7 has its lower edge rolled over and slides freely in said guideway andis also notched as shown at 8 and is provided with a suitable integralpost or thumb piece 9 by means of which it can be moved along theguideway 5. A suitable rod 10 has its inner end upwardly turned as shownat 11 to engage the inner face of the flue wall, and said rod extendsoutwardly between the pipe 3 and the thimble 2 and has loosely connectedto its outer end a rod 12 and said rod 12 has a double angled endportion 13 a portion of which is adapted to be brought into engagementwith the notches 6 and 8.

The usual ornamental collar 14 fits over the stove pipe and bearsagainst the outside of the chimney wall, said collar being slotted asshown at 15 to permit passage of the rods 10 and 12.

When the parts have been placed in posi tion the plate 7 is adjusted inthe guideway so that it will bear against the collar 14: therebypreventing any movement of said collar along the pipe 3, and the rod 12is drawn outwardly so as to bring the upturned end 11 of the rod 10 intoengagement with the wall of the flue, as shown in Fig. 1, and the angledend portion 13 is then brought into engagement with the alining notches6 of the guideway 5 and in one of the notches 8 of the plate 7. This notonly locks the pipe 2 in position but also locks the slidable plate 7What I claim is 1. The combination with a stove pipe, a notched guidewaycarried thereby, a slidable and notched plate working in the guidewayand means adapted to engage the inner wall of a flue and also adapted toengage notches of the guideway and slidable plate.

2. A device of the kind described comprising a stove pipe and a collarfitting thereupon and adapted to encircle the pipe opening, a notchedguide way carried by the stove pipe, rods loosely connected together,one of said rods being bent to engage the inner wall of the flue, andthe other rod being bent to engage the notches of the guide way, and anotched plate slidable in said guideway and adapted to engage saidcollar, the last mentioned rod also looking said slidable plate inposition in the guideway.

3. A device ofthe kind described compris ing a thimble adapted to fitwithin a flue, a stove pipe adapted to fit within said thimble, a collarcarried by the stove pipe, means arranged between the pipe and thethimble for engaging the inner face of the flue, a vertically arrangedguideway having its upper edge notched, said guideway being permanentlysecured to the stove pipe, a rod loosely connected to the flue engagingmeans having an angled end portion adapted to engage notches of theguideway, and a plate normally bearing against said collar, the

said collar having an opening to permit passage of said rod.
